eXAmPle:
For a ∆T 20K, of a MODULEX 250, the maximum
water flow rate required is 10514 l/h.
The graph of the boiler pressure drops shows that
the pump must ensure a head of at least 1.6 m/h

NOTE:
It is always advisable to use a hydraulic separator (*) between
the boiler circuit and the system.

2.4.2 - DETERMINATION OF ThE PRIMARY CIRCUIT PUMP OR BOILER PUMP
The pumps must be determined by the installer
or designer according to the boiler and sys-
tem data.
The boiler pump must have head that is able to ensure the
pump's flow rates according to the circuit's
∆
t.

The pump is not an integral part of the boiler.
It is recommended to select a pump with a flow rate
and head of approximately 2/3 of its characteristic
curve.
